Multi-phase DC-DC PMIC: the efficient, space-saving choice for today's application processors
More InfoLess Info
'Faster, Smaller, Better': these are the goals for new mobile power microelectronics designs. This means that the power management IC (PMIC) has to provide more output power at higher efficiency and smaller PCB area. To solve this, ams offers the AS3729, a multi-phase power supply power stage external to the PMIC. It keeps connectivity losses to a minimum while implementing an innovative control interface which needs only 1½ lines per phase. Read this paper to learn more.
